SNAP-FASTENER.

Specification of Letters Patent. 'Pgmtgntgd Sept '7, 15220,

Application filed January 14, 1914. Serial No. 811,971.

To all whom it may concern v Be it known that we, ELIZABETH J. SMITH andDOUGLAS SMITH, both citizens of the United States of America, residingin Larchmont, in the county of Westchester, and State 3 of New York,have invented certain new and useful Improvements in SnapFasteners, ofwhich the following is a specification.

This invention relates to separable fastenors, more particularly snapfasteners, and aims to provide improvements therein. The

present invention provides a pronged device. which may be cheaply andsimply manufactured, which iscapable of being applied to fabrics, andparticularly to light fabrics such as are used for ladies dresses or thelike, in such manner as to be securely attached thereto withoutmutilation of or damage to the goods. The fastener. is als'o'one whichis capable of being applied to goods with, great rapidity, and eitherby. hand or by use ofa machine.

Figure 1 illustrates a sectional view with the parts in united position.Fig. 2 is a bottom plan view of. the parts shown in Fig. 1.

Fig. 3 is a sectional view of the socket member illustrated in Fig. 1. I

Fig. 4 is a top plan view of the said socket member.

Fig. 5 isa sectional view of the ballmember'illustrated in Fig. 1.

Fig. 6 is a top plan view of said ball member.

Fig. 7 illustrates further an embodiment of the invention, a top planview of one member being shown.

Fig. 8 is a view similar to Fig. 7, illustrating a still furtherembodiment of the invention. i

Fig. 9 is a top plan view of a socket member, with parts shown insection, illus trating a further embodiment.

Numeral 1 designates the base piece of the fastener member; 2, thesocket part; 3,the

ball part; and 4, the prongs.

The fastener members are preferably formed of sheet metal, and the balland socket formed by appropriate metal-working op erations.

Furthermore, in order that the goodsmay liens fiat as possible over theball'and socket members, they base part of the fastener may i be bentbac'kwardly'or upwardly, toward the back of'the socket, as shown inFigs. 1 and 3. From Fig. 1 it will be seen that the goods are broughtrelatively close-together by the fastener, it being understood thattheproportions are considerably exaggerated in the drawing. g

In order to obtain a resiliency 1n the ball or socket, or both, the ballorsocket, or both.

may be made with portions out out there from as indicated at 5. V

The prongs 4 are preferably formed by tener, and preferably of the metalof the base piece. .The cut out portion of the metal which is left aftercutting out the prongs 4 may constitute'the cut out portions 5,-whichare provided in the ball or socket, or both. V In order that the prongedfastener may be attached to fabrics, and especially to light fabrics, insuch manner as to be firmly and securely attached thereto, and withoutlocal} izing the strains transmitted by the fastener to the goods at thebends of the prongs, it is desirable that the prongs should clasp thegoods between themselves and the firm part of the fastener member orbase piece. It is also desirable that the prongs shall overlap closetogether upon the face of the goods. 7 The prongs 4, are, for theforegoing considerations, preferably formed somewhat long, narrow andtapering, and with a flat side adapted to be pressed against the goods.A fastener member or base piece is also provided with firm portions 7against which the prongs are adapted to be pressed when turnedoveragainst a piece offabric to which the fastener is attached. 'Asshown nFigs. 1 to 5 inclusive, the portions 7 lie between the cut out portionsleft after cutting out the prongs 4, and the'pron'gs are pressed againstcuttin them out of the metal of the fasthe portions 7 by turning them toone side in bending so that they will lie'to one side of the base piece,as shownin Fig. 2. This may be accomplished'by hand or by a suitablemachine, as above stated.

1 The spring 1s In Fig. 7, prongs are shown as cut out of the marginalportions of the base piece. In

this construction the prongs are turned back upon themselves upontheportion 7 of the base piece, which portion 7 lies opposite theportions of the base piece from which the prongs are out. By thisconstruction the prongs may be made to overlap, without beingsuperimposed, upon the face or the goods.

In Fig. 8, a member is shown wherein the prongs are cut out of .themetal beyond the edges of the base piece. As shown, the prongs on oposite sides of the fastener memher are pre erabiy slightly staggered, in

order that the prongs when bent over on the base piece may lie side byside without being superimposed upon one another. The base piece may beslit at points Gin order that the prongs may have a straight bend.

A socket member having resilient means for retaining a ball membertherein may be manner as not 4, when turned against the solid portion 7of the base piece.

Such a spring is place by a bent-over spring may be held in the head ofa lug 10 struck up from the metal of the basepiece. I

2. A member of a separable-fastener having prongs thereon, aprojectingsocket-pieee, a spring attached to said fastener and havingparts adapted to project through said socketpiece to engage a ballmember when inserted in said socket-piece, said fastener member having asolid'base-portion against which said prongs are adapted to be pressed,said spring being out of the way of said prongs when said prongs arepressed against the solid-portion of said base-piece.
